Would the dissolved CO2 have a negative impact on the microbial and enzymatic processes that play a vital role in my grow, either at the canopy level or at the rhizosomal level?

Interesting thought, I would be interested to see if there are any previously published white papers in regards to PH changes fighting of pest and disease.

When you say, “traditional,” do you mean like this? https://www.leafly.com/news/growing/co2-for-growing-marijuana-plants

Can you give us a ballpark MSRP?

That would be a good reference yes.

I can tell you pH absolutely works to control fungi/molds @bryan.eden

Time to do some googling!

At the lettuce trials at the University of Guelph, we achieved 33% and 100% increased lettuce biomass using dissolved CO2 versus CO2 gassing at 800 PPM in side by side grow chambers.
They are not directly comparable as atmospheric CO2 exposes both CO2 sources and sinks. We only apply dissolved CO2 for specific plant leaf surface areas only that are sinks.

Cannot do that until we get specific information on your grow room configuration.

I remember back in the day we used to add baking soda to our sprays to prevent molds and mildews. Worked well, didn’t realize it was because we were causing Ph disruptions.

What are the comparative costs of the dissolved CO2 and gas?

Yes - I have been to the Leafly website and they present CO2 gas usage for cannabis very well.

Can you tell us what corresponding changes were made in other additives, to achieve this? (More or less fertilizer, etc.?)

Thanks for adding that @Kareenabis420!

It is a combination of proven 33% accelerated cannabis plant veg growth times 60% of a full grow cycle or a net 20% and 22% large bud weight in our first press released grow trial this AM.
We used SGS Labs to verify our bud THC, CBD and CBN concentration which were essentially the same as our control group buds grown without additional CO2 gassing.

Is this something that has to by applied by hand, or can sprayers be permanently set up to turn on when needed?
